It might not get hot enough, as it should be designed not to burn your hair
Search for "heat gun" on amazon.com, I'd go for something like http://www.amazon.com/Porter-Cable-P...words=heat+gun
which has a variable temperature setting. The heat switch might activate anywhere between 60°C and 120°C, you'd have to check the data sheet if there's no temperature indicated on the device (and if it's a switch at all).
For testing, and as it currently has no continuity, you could simply short the sensor and see if it makes any difference.
With best regards
